We are using AEM 5.6.1.20130606 and have a problem with metadata not showing up for one particular video. So basically I go to "/damadmin#/content/dam/...mp4" and the title, description and all other fields are empty.
Looking at the network tab in Chrome I saw the XHR request for "....mp4/jcr:content/metadata.infinity.json".
The problem now seems to be that this request returns "300 Multiple Choices":
....mp4/jcr:content/metadata.2.json
....mp4/jcr:content/metadata.1.json
....mp4/jcr:content/metadata.0.json
For any other assets that I tested it returns a 200 and just one JSON result.
Has anybody seen this before?
